Utility model content
For the problems referred to above, the utility model designs a kind of punching cutting die.
The technical solution of the utility model is as follows:
A kind of punching cutting die, comprise blade, knife rest, shaped block, locating piece, carve tight sheet, filling cotton, blade is a through hole, be divided into working end and positioning end, working end is cutting edge, and filling cotton and shaped block are arranged on blade hollow space, filling cotton press-in blade operative end, shaped block embeds blade positioning end, blade is fixed on knife rest by shaped block, and knife rest is square, and one jiao has chamfering, corner is equipped with locating slot, and locating piece is riveted tightly be arranged in locating slot by being carved tight sheet.
Preferably, described blade adopts high-speed steel or wolfram steel forging molding.
Preferably, described filling cotton adopts the cotton products that coefficient of elasticity is large.
Preferably, a uniform 10-20 installing hole on described knife rest, for counteredge.
Preferably, described blade operative section is oval, is equipped with other working section blades of identical positioning end.
According to technique scheme, the utility model provides a kind of and utilizes the job step of above-mentioned instrument in the processing of plastic uptake holes of products class formation:
1. clear up cutting machine table top, severing backing plate, cutting die are installed, sanction is sat propelling movement and puts in place, connect cutting machine power supply, open equipment configuration switch, set cutting machine stamping-out height, after completing setting, close clicker press machine configuration switch;
2. being inverted by plastic workpiece to be processed is placed on cutting machine workbench;
3. pair punching cutting die locating piece and plastic workpiece to be processed position tool setting, guarantee that Working position is correct;
4. press undershoot switch, punching cutting die starts undershoot operation;
5. after punching cutting die completes punching operation, go back up to original position, by punching cutting die and separation of products, take out product;
6. filling cotton will excise clout ejection, and clear away waste, completes punching processing.
The utility model has the advantage of:
1. the processing technology of this cover instrument can complete the plastic cement products punching processing of slight step (hole is not in one plane) very well;
2. knife rest as required, can install the blade that quantity is different, the hole of processing varying number and position;
3. the processing of this punching cutting die is with installation period compared with the equivalent effect punched hole punching pressing mold process-cycle, can save for 80% time;
4. processing cost reduction by more than 90% compared with equivalent effect punched hole punching pressing mold of this punching cutting die;
5. the process flexibility of this punching cutting die comparatively punched hole punching pressing mold greatly improve.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the utility model is described in detail, but is not limited thereto.
Embodiment 1,
As Figure 1-5, a kind of punching cutting die, comprise blade 1, knife rest 6, shaped block 3, locating piece 5, carve tight sheet 4, filling cotton 2, blade 1 is a through hole, be divided into working end and positioning end, working end is cutting edge, filling cotton 2 and shaped block 3 are arranged on blade 1 hollow space, filling cotton 2 is pressed into blade 1 working end, and shaped block 3 embeds blade 1 positioning end, and blade 1 is fixed on knife rest 6 by shaped block 3, knife rest 6 is square, one jiao has chamfering, and corner is equipped with locating slot, and locating piece 5 is riveted tightly be arranged in locating slot by being carved tight sheet 4.
As shown in Figure 4, blade 1 is hollow, and shaped block 3 contacts with filling cotton 2, and in punch process, excised the waste material compression filling cotton 3 of workpiece to be processed by blade 1, waste material is released blade 1 by the filling cotton 3 recovering shape after completing punching.The blade 1 of hollow only has cutting edge to contact with workpiece to be processed, its resistance run into is less, if when being processed with the workpiece of tiny step, and can before workpiece generation Light deformation, just touch next stage step to process it, prevent the problem of being out of shape aft-loaded airfoil deviations.Blade 1 is elliptical section, if need to process other shape holes, as square opening, tri-angle-holed etc., can use the blade 1 of other cutting edges of equivalent specifications positioning end instead.
